Device for testing concrete under impact tensile loading and lateral compression

Abstract

At the Delft University of Technology the dynamic material response of concrete is being investigated, using the split Hopkinson bar technique (SHB). To gain more insight into the influence of the initial stress conditions on the dynamic response, the SHB has been combined with a static compression loading device perpendicular to the SHB. This paper describes the test set-up, the monitoring techniques and the tests performed during the development of the biaxial loading device. Special attention is paid to the interaction of both loading devices in the biaxial set-up.
